Abstract

An ultrasonic diagnostic imaging system includes a CMUT transducer probe (10) with an array of CMUT cells (10') that can be configured to operate in different frequency ranges and with different acoustic element pitches for different clinical applications. The frequency response of the CMUT cells can be tailored for different clinical applications by increasing the DC bias voltage for higher frequency clinical applications, or decreasing the DC bias voltage for lower frequency applications. Individual acoustic elements including groups of CMUT cells can be configured to have a desired pitch that is optimal for the frequency being used for the imaging application.
